    Right. The real interesting part is how easily we've managed to locate planets, and now we can see that planets in this zone are not very rare. (a second planet in the goldilocks zone was found in the same system!) Given the sheer number of stars out there, this greatly ups the odds that there's other planets out there capable of supporting life.

    When I went to school a planet with the same diameter as Earth but with a mass 3 to 4 times Earth would have a surface gravity 3 to 4 times Earth standard..... anyone have an explanation as to why physics has changed in the last 30 years?

    Another big draw back to a tidally locked planet would be the constant hurricane force winds cause by convection between the dark side and the light side...... you would have to live under ground.

    The "goldielocks zone" is determined by the type of star more than anything else. When determining if a planet really is "Earthlike", the planet itself will be looked at as well as it's location in the solar system.

    The designation of Earthlike here is somewhat misleading because this planet isn't really "Earthlike". It's has a tidal lock orbit, which is very unearhtlike, and a 37 day orbital preiod (also very unearthlike.

    In truth, the planet is being called Earthlike because it has th epotential to have liquid water in the secondary "goldilocks zone" created by the Terminus (which is the divider between night and day on a planet, in cases wher eth eplanet is tidally locked, the terminus is stationary and thus represents the "moderate tempurature" zone).

    We also know nothing about it's atmoshpere that I was able to see. If the atmosphere is not earthlike, it might not be habitable for humans. According to the article, it's gravity should be somwhere close to that of Earth, which does make it "Earthlike" in that sense.

    From what I can tell, labelling it as "earthlike" is misleading, but it does have the potential of being habitable by humans providing it has the right conditions necesary for human life to exist on it in the terminus (teh right conditions would be many of those that Tashah mentioned).

    It is also possible that life evolved on the planet, but technically that is even possible in places that fall outside the are we call the "habitable zone". We have a very limitted dataset with which we are working when we make claims about "habitable zones". We are only looking at one instance of the development of life amongst what may potentially be billions of instances (or it may potentially just be one. We have far too many unknowns to make any definitive claims. It is all speculative).

    In other words, we cannot genralize data from a single specific instance to the entire universe. All we can say is that the "habitable zone" was a prerequisite for creating life as we know it here on Earth. We are assuming that Earthlike planets found elsewhere will also have the ability to produce life, but that is not a given, nor are the conditions that were necesary for life on EArth necessarily required fo rthe formation of life in general.

    You learned physics wrong. (well, not really, but that diameter thing is important)

    The convection thing might happen, but that requires a lot of speculation about the composition of the atmosphere (if it even has an atmosphere), layout of the land, etc.

    The Earth is going to be consumed eventually by our Sun as it expands as it dies.

    We need a place to go and set up our civilization unless this and other planet that meet our needs are otherwise inhabited by other beings.

    I think you did not pay close enough attention.

    This planet is being refferred to loosely as the goldilocks planet because it exists in a proximity to it's star where the temperature would be within a range to support some life. We have no idea if water exists on it or any of the other elements needed for life to be sustained. They have no idea what gases make up the atmosphere of this planet or eve if it has one.

    The planet orbits in such a manner relative to its rotation that one side is always dark the other is always lit. Both of these areas would make it difficult for life such as our species to live.

    I think you may be overestimating the distance from us as well it is not really " nearby ".

    Before anyone can think of visiting it we would have to find a way around those pesky laws of physics which prohibit lightspeed travel.

    On an astronomical scale, it's just down the street.

    Normally I'm opposed to human trafficking but I'm willing to make an exception.
